Abstract

1. Rigid and resistant passive obstacle for the defense against vehicles, characterized by being formed by four hollow conical legs arranged in such a way that their ends define a tetrahedron and join together in a knot in the center of the tetrahedron. 2. Rigid and resistant passive obstacle for the defense against vehicles, characterized by being formed by four truncated pyramidal legs arranged in such a way that their ends define a tetrahedron and join together in a knot in the center of the tetrahedron. 3.
